  • typical type II membrane protein, which is localized in the Golgi apparatus
  • basic FUNCTION
  • participating in O-mannosyl glycan synthesis
  • catalyzing the transfer of GlcNAc to O-mannose of glycoproteins
  • promotes Glioblastoma multiforme (GBM) progression via activation of CTNNB1
  • is a Golgi glycosyltransferase that catalyzes the formation of the N-acetylglucosamine (GlcNAc) beta1&
  • 8594;2Man linkage of O-mannosyl glycan
  • is glycosylated by mucin-type O-glycans

    small molecule cofactor,
  • Mn2+
  • protein
  • DAG1 and LARGE for a convergent post-translational processing pathway during the biosynthesis of dystroglycan in the muscle
  • alpha-dystroglycan, a substrate of POMGNT1, is concentrated around the blood vessels, in the outer plexiform layer (OPL), and in the inner limiting membrane (ILM) of the retina
  • interacting with FKTN
  • GOLPH3 was found to bind to POMGNT1 which is involved in O-mannosylation of alpha-dystroglycan (novel role for GOLPH3 in mediating the Golgi localization of POMGNT1)
  • POMGNT1 stem region modulates O-mannosylation sites of DAG1, by its carbohydrate-binding domain

  • altered glycosylation of Alpha-dystroglycan may be responsible for the reactive gliosis and reticular fibrosis in the retina, and the subsequent developments of retinal dysplasia, abnormal ERGs, and retinal detachment in the mutant mice
